Re: [APML] S Monoceros Nebulosities with Schmidt

[Chris Schur <comets133@yahoo.com>]

Jim, thanks!  I usually do the minimum filter thing to
most schmidt shots, but on this one, the nebula is so
bright that I felt the "wow" factor was enhanced by
the sheer number of stars.  A completely asthetic
thing!

I am finding that the red halation problem with supra
is increasing with the age of the film, I spend more
time now making sure the reds dont get carried away.
